Simarouba is the bark of a tree which grows in Guiana. 
It is yellowish white, odorless, slightly bitter tasting, 
composed of pliant fibers attached to the white, light, 
insipid wood of the racemes, shoots, and tronk, from which 
it is readily separated. Simarouba is composed of resinous 
gum of a not unpleasant taste. It fortifies the stomach by 
its slight bitterness, appeases pains and cramps by its 
balsamic and unctuous properties, and arrests hemorrhages 
and flux [dysentery] by its astringent and vulnerary virtue. 
This bark was first brought to France in 1713 from 
Guiana, where it is used for dysentery. In 1718 de Ju^tsieu 
employed it successfully in the treatment of dysentery fol- 
lowing fever. Some directions are given for its use 
(v. 2, soc.l, pp. 363-367).
